Information on Frostytech's test methodology is available here.
The Heatsink Fan:

The blue squirrel cage fan is constructed of two 25mm tall sections placed together end-to-end, surrounded by a cylinder of knife-edged aluminum fins. The fan draws air in from the top of the heatsink, through the fins. The translucent plastic cover protects the tops of the heatpipes, and holds in the clear plastic cover which prevents air from being drawn in by the top of the cooler. The Gigabyte 3D Rocket Cooler-Pro PCU22-VG connects with a standard 4-pin molex power connector, and includes a single wire RPM signal cable for the motherboard fan header.

Heatsink Top:

The fan is firmly attached inside of the aluminum finned section, but we managed to remove it so you can get a better sense of how this heatsink is put together. Note how the heat pipes run down through the fins, to the copper base. The circuit board on the top of the cooler controls the fan speed when the potentiometer is plugged in. It also supports the four very bright blue LED's which illuminate the top of the Gigabyte 3D Rocket Cooler-Pro heatsink.

Heatsink Side A:
The 3D Rocket Cooler-Pro PCU22-VG heatsink stands about 115mm tall, making it a pretty big cooler to contend with - so make sure you have sufficient room in your case first. The forged copper base is about 6mm thick on average, and connected to the rest of the heatsink by the four 6mm diameter copper heatpipes. The cylindrical aluminum fin array measures 80mm tall by 83mm wide. Note the translucent plastic skirt 2/3rds down which is used to direct exhaust towards adjacent motherboard components (to cool them).

The upper 43mm section of fins should really have the same knife-edge treatment as all fins do on the inside, since air is drawn into the heatsink through this section. It does not, indicating to us that this heatsink is a retrofit to the original design which operated in a different manner.

Heatsink Side B:
The 54 aluminum fins measure 0.4mm thick, and are spaced approximately 0.8mm apart. The fins have been nickel plated to facilitate soldering with the copper heatpipes. The copper base is capped with a small section of stainless steel, and it is over this that the K7 and K8 clip mechanisms rest to hold the Gigabyte 3D Rocket Cooler-Pro heatsink in place. The socket 478 clips rest on the small copper tabs visible in the picture. Installing the heatsink isn't all that complicated, since it is a tool free unit. It's vital to make sure the heatsink is oriented properly for each particular socket, and processor type. Note the power controls at the top of the heatsink for fan and fan speed controller.

Heatsink Base:

The forged copper base of the Gigabyte 3D Rocket Cooler-Pro is well machined from and measures about 40x40mm in size. Being forged, the copper is a little more stiff than with a traditional punched sheet metal base, and takes the machining smoothly. The surface finish is very good (~16 microinches), and surface flatness is excellent according to our straight edge test. The Gigabyte 3D Rocket Cooler-Pro comes with a small pack of thermal compound to make installation a breeze.
